Patent number: 7205173Abstract: A MEMS incorporating a sensing element and a JFET electrically connected to the sensing element is fabricated by the steps of: forming a first layer of electrically insulating barrier material on a surface of a substrate; patterning the first layer so as to expose a first region of the substrate; doping by ion implantation the first region of the substrate to form a well region of the JFET; forming a second layer of barrier material on the surface of both the first layer and the first region of the substrate; patterning the barrier material so as to expose a part of the first region of the substrate; doping by ion implantation the exposed part of the first region of the substrate to form source and drain contact areas of the JFET; patterning the barrier material so as to expose a second region of the substrate; and doping by ion implantation the second region of the substrate to form gate and substrate contact areas of the JFET in a single implantion step.Type: GrantFiled: March 19, 2003Date of Patent: April 17, 2007Assignee: QinetiQ LimitedInventors: Kevin Michael Brunson, David James Hamilton, Robert John Tremayne Bunyan, Mark Edward McNie

Patent number: 7112501Abstract: A fabrication process for a silicon-on-insulator (SOI) device includes defining an active region in an SOI substrate, doping the entire active region with an impurity of a given conductive type, masking a main part of the active region, and doping the peripheral parts of the active region at least two additional times with an impurity of the same conductive type, preferably using different doping parameters each time. The additional doping creates a channel stop in the peripheral parts of the active region, counteracting the tendency of the transistor threshold voltage to be lowered in the peripheral parts of the active region, thereby mitigating or eliminating the unwanted subthreshold hump often found in the transistor operating characteristics of, for example, fully depleted SOI devices.Type: GrantFiled: October 20, 2003Date of Patent: September 26, 2006Assignee: Oki Electric Industry Co., Ltd.Inventor: Masao Okihara

Patent number: 7112499Abstract: A process is described to form a semiconductor device such as MOSFET or CMOS with shallow junctions in the source/drain extension regions. After forming the shallow trench isolations and the gate stack, sidewall dielectric spacers are removed. A pre-amorphizing implant (PAI) is performed with Ge+ or Si+ ions to form a thin PAI layer on the surface of the silicon regions adjacent to the gate stack. B+ ion implantation is then performed to form source/drain extension (SDE) regions. The B+ implant step is then followed by multiple-pulsed 248 nm KrF excimer laser anneal with pulse duration of 23 ns. This step is to reduce the sheet resistance of the junction through the activation of the boron dopant in the SDE junctions. Laser anneal is then followed by rapid thermal anneal (RTA) to repair the residual damage and also to induce out-diffusion of the boron to yield shallower junctions than the just-implanted junctions prior to RTA.Type: GrantFiled: January 16, 2004Date of Patent: September 26, 2006Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Chyiu Hyia Poon, Leng Seow Tan, Byung Jin Cho, Alex See, Mousumi Bhat
